For $460 on the MoBo / CPU combo, I'd get one of these for a gaming rig (HT does nothing for you in gaming)
Asus P8Z77 Pro w/ 3570k - $415

But again, you said video editing so that's where HT comes in handy and that's $80 more at $540

The Noc loses out in performance, aesthetics and warranty to the Phanteks (5 year warranty)

Intel 520 is a Tier 5 SSD (120 GB second-gen SandForce SSDs with Sync ONFi NAND) .... 46 % drop in performance from the Tier 1's
I'd suggest a Tier 1 for $200 - 240 GB second-gen SandForce SSDs with Toggle NAND include the Mushkin Chronos Deluxe, Patriot Wildfire, OCZ Vertex 3 Max IOPS, Kingston HyperX 3K, OWC Mercury Extreme Pro 6G, Corsair Force GS and the non SF Samsung 830 and Plextor M3 Pro

Drop the sound card, MoBo sound is more than adequate
Case has no USB 3 ports and is way outta line with the quality of your other components.
Corsair 500R ($120) w/ HX850 ($165) btw, despite what pcpartpicker says, ncix wants $212. If not going for maximim OS's , you can get away with the TX750

Id recommend a 120Hz monitor if ya can squeeze into budget if gaming is highest priority .... IPS panels however rule for image editing tho....and "not bad" gaming monitors. You'll have to decide which is more important.

The screen was tested using the chase test in PixPerAn, a good bit of software for trying to quantify differences in real terms responsiveness between monitors. As a reminder, a series of pictures are taken on the highest shutter speed and compared. The images above are the best case examples from the U2312HM with the overdrive (OD) function disabled and then enabled. When OD is turned off there is a more pronounced motion blur which is noticeable to the naked eye. It doesn't have any severe ghosting but the blur is certainly more obvious. When you enable OD the blur is reduced but there is still some minimal motion blur detectable. While the blurring is improved quite nicely, the OD impulse does introduce a bit of an overshoot in the form of a dark trail behind the moving car. This is caused by the aggressive application of an overdrive impulse, causing the pixels to change orientation too far before reverting to the desired position. This characteristic trailing can happen on screens where overdrive impulses are applied, where it is either too aggressive (to try and boost response times even more) or poorly controlled.
Like the U2412M, in the case of the U2312HM this is not too bad and should not prove a major distraction during normal use. We will look at the screens performance in more detail in a moment, but from a pixel response time point of view it is beneficial to have the OD function turned on (as it is by default). This was a very similar story to the U2412M which performed almost identically in these tests.
